INrER AL-coMBUsr'IoN ENGINE,

To all whom it may concern:

Be it known that I, RAY H. CHASE, a

citizen of the United States, residing at Alexandria, in the county of Hanson, State of South Dakota, have invented a new and useful Internal combustion Engine; and I do hereby declare the following to be-a full, clear, and exact description of the inventlon,

such as will enable others skilled in the art to which it 'appertains to make and use the same.

The inventionrelates to internal combustion engines and hasfor its object to provide an engine of this character, wherein as the connecting rods to the pistons by a ball and socket connection so that they may be easily revolved.

A furtherfobject isto provide cooling means for the cylinders around their SlClQS' and also provide the cylinders with plugs at their upper end,- which plugs are hollow, thereby forming chambers for the reception of-water so that the upper endsgof the cylinders may be cooled as well as the vertical walls of the cylinders. Also to provide siphoning means whereby when the water is drained from the water jacket, the water in the chambers of the cylinder plugs will be siphoned out of the chambers of the plugs.

With the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what s claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of an engine, parts being broken away to show the position of the cylinders and crank shaft.

Referring to the drawings the numeral 1 designates a four cylinder internal com bustion engine, said cylinders being designated by the numerals 1, 2, .3 and 4. The cylinders are surrounded by a water jacket 5 to which water is fed from the chamber 6 of the cylinder head casting 7 the end 8 of which may be connected by a pipe to the radiator of the vehicle. Extending downwardly from the cylinder head 7 are cylinder plugs 9 which are provided with water chambers 10 into which water passes from the chamber 6 through the apertures 11, thereby providing means whereby rricsj? will be cooled as well as the body of the I cylinders.'- Pipes 12 are disposed in the water jackets 5 and have their upper ends bent as at 13 so that downwardly extend in'g portions 14 are formed,'the portions 14 being disposed in the chambers 10, of the cylinder plugs 9. When the water is drained from the jacket 5, the pipes12 will siphon the water from the chambers 10 of theplugs 9, therebypreventing the water from freezing in the plugs, which often causes the cracking of the same.

Rotatably mounted in bearings 15 of-the crank casing 16 is a crank shaft 17 and connectedfl'to the crank shaft as at 18 are connecting rods 19, theupper ends of which are connected tothe. pistons 20 by ball and socket joints 21. The. pistons 20 are adapted to reciprocate in the cylinders and at the.

same time rotate, said rotation'being so timed with the reciprocation that the usual cycles of operation Will take place in connection with intake and exhaust ports. Each piston 20 is provided at its upper end with a chamber 22, the wall of which is provided with a port 23, which port serves the double function of an intake and exhaust port. The pistons at their lower ends are provided with vertical slots 24 forthe reception of lugs 25-, carried by rotatablegears 26 which surround the lower ends of the pistons. These gears 26 are in mesh with each other and are supported in horizontal relation to each other and in mesh 7 by means of brackets 27, which form bearings for the gears. Avertical shaft 28 is mounted in a bearing 29 at one end of the operation.

- 7 the po,wer stroke, however a bevel gear which meshes with a bevel gear 32 carried by the crank shaft 17. ears 30, 31 and 32 are of such a size,

thatwlien the crank shaft 17 makes a half revolution, the gears in which the pistons reciprocate will cause the pistons to make a quarter revolution, thereby taking each cylinder through the usual four cycles of For instance in thecase of the cylinder number 1, as the piston 20, starts downwardly, the port 23, will pass the intake port 33, thereby sucking or allowing the entrance ofthe gases into the combustion chamber, during thisdownward movement the port23 will have movedninety degrees and the crank shaft one'hundred eighty degrees, then the piston 20' starts upwardly on a compression stroke thereby compressing thecharge, by this time the'piston will have revolved one hundred eighty degrees and the crank shaft has made a completed revolution.- The charge, having been compressed the same is fired bythe spark plugs 34 and the piston moves downwardly on the piston will during this downward movement move ninety'degreesin rotation making a total rotation of two hundred and seventy grees and the'crank shaft making a total rotation of one and a half rotations. At the end of the power stroke the piston starts upwardly," during which upward movement the same is rotated ninety degrees which completes a cycle of operation, however during this upward movement theport 23 passes the exhaustport 35, thereby allowing the exhaust of 'the products of combustion. The operation of the other cylinders is the same, with the exception that the pistons in the cylinders 2 and 4: revolve in the opposite direction to the pistons in the cylinders 1 and 3. g

the upper end thereof being Secured two subscribing witnesses," 7

I From theabove it will be seen that an" internal, combustion engine is provided, wherein the use of valves is eli'minated and one wherein the timing will be positive at alltimes. It will also be seen that by the use of the chambered plugs, which extend into the upper ends of "the cylinders, that the cylinders will be thoroughly and'completely cooledatthe tops of the explosion chambers. It is to' be understood that various types of ball and socket connections may be used to connectthe connecting rods to the pistons, or if so desired roller. bearings maybe used. 1 7

The invention having been set forth, what is claimed as new and useful is An internal combustion engine comprising casing having a cylinder .therein, la crank shaft rotatably mounted in the casing,'said crank shaft being provided with a connecting rod, a piston universally connected to the upper end of the connecting rod and disposed in thecylinder, the upper end of the piston being provided with a chamber, port in the wall of the piston and in communication with same chamber, said combined intake and exhaust portbeing restricted centrally, elongated intake and exhaust ports in the wall of the cylinder, said a combined intakeand exhaust intake and exhaust ports being angularly it arranged and so positioned that as the piston rotates and simultaneously reciprocates V the exhaust and intake ports willbe main- In testimony whereof I: have signed my tained in registration-with the combined name to this specificationin the presenceof I V v RAY 1H," CHASE.
